Chasing the Buzz: A Complete Guide to Cicada Fly Fishing on the Green River
As a fly fishing guide and outdoor writer for over a decade, I’ve witnessed some incredible hatches, but few compare to the explosive energy of a cicada hatch on the Green River in Utah and Wyoming. The sheer volume of these insects emerging from the ground creates a feeding frenzy for trout, and knowing how to capitalize on it can lead to some of the most memorable fly fishing cicada experiences of your life. This guide will cover everything you need to know about the Green River cicada hatch, including timing, cicada fly patterns, techniques, and essential gear. We'll dive deep into maximizing your success during this phenomenal event.
Understanding the Green River Cicada Hatch
The Green River’s cicada hatch isn’t an annual event; it’s periodical, meaning it occurs every 13 or 17 years depending on the specific brood. The most recent significant hatch was in 2023, and the next major one isn’t expected for another decade or more. However, smaller, localized hatches can occur in between these major cycles. These smaller hatches are often triggered by localized environmental conditions. The timing of the hatch is heavily influenced by water temperature and soil moisture. Generally, it peaks in late July and August when water temperatures are warm and the ground is dry. (National Park Service - Green River Fishing)
What Makes This Hatch Special?
Unlike mayflies or caddisflies, cicadas are large, clumsy fliers. They literally fall onto the water, creating a significant disturbance. Trout key in on this easy meal, often ignoring other insects in the process. This makes the hatch incredibly effective for anglers, even those relatively new to fly fishing. The size of the cicadas also means you need to adjust your approach and gear – we’re talking about big flies and potentially heavier tippet.
Essential Cicada Fly Patterns
Choosing the right cicada fly patterns is crucial. While trout aren’t overly picky during a heavy hatch, having a variety of patterns that mimic the size and color of the local cicadas will increase your chances of success. Here are some of my go-to patterns:
- Foam Cicadas: These are incredibly buoyant and easy to see, making them ideal for fishing fast water or when you need a dry fly that won’t sink.
- Rubber Legged Cicadas: The rubber legs add a lot of movement and realism, attracting trout from a distance.
- Turk’s Tarantula: While not a direct cicada imitation, this pattern’s size and profile often work well during the hatch.
- Wiggle Cicadas: These patterns utilize articulated bodies to create a lifelike swimming action.
- Large Stimulators: In a pinch, a large, dark stimulator can also imitate a cicada, especially when paired with a dropper.
Sizes typically range from #6 to #12, depending on the size of the natural cicadas. Colors to consider include tan, brown, olive, and black. Don’t be afraid to experiment! I always carry a selection of each type in multiple sizes and colors. (REI Expert Advice - Fly Fishing Cicadas)
Nymphing During the Hatch: Don't Forget Below the Surface
While the dry fly fishing is the main attraction, don’t overlook the opportunity to fish nymphs. Trout will often feed on the drowned cicadas that sink to the bottom. Large stonefly nymphs or weighted cicada imitations can be incredibly effective. A dropper nymph, suspended below your dry fly, can also be a great way to cover more water and increase your hookup rate.
Techniques for Fly Fishing Cicada Hatches
Successfully fly fishing cicada hatches requires a slightly different approach than traditional trout fishing. Here’s what I recommend:
- Presentation: Accuracy isn’t as critical as with smaller flies. The goal is to get the fly in the vicinity of feeding trout. A sloppy cast is often forgiven during a cicada hatch.
- Retrieval: Let the fly drift naturally. A slight twitch or strip can sometimes entice a strike, but generally, a dead drift is best.
- Stepping Up Your Tippet: Cicadas are large, and trout aren’t shy about taking them. Use heavier tippet (3X-4X) to avoid break-offs, especially when fishing around structure.
- Focus on Structure: Trout will often congregate near structure (rocks, logs, undercut banks) to ambush cicadas.
- Listen for the Buzz: The sound of cicadas is a good indicator of where the hatch is most concentrated.
Don’t be afraid to cover water quickly. If you’re not getting strikes, move to a new location. Trout will often be concentrated in specific areas during the hatch. I often tell my clients to think about "chunk and change" – make a few casts, and if nothing happens, move on.
Gear Recommendations for the Green River Cicada Hatch
Having the right gear can make a big difference in your success. Here’s a checklist of essential items:
| Item | Recommendation |
|---|---|
| Rod | 6-8 weight fly rod |
| Reel | Matching reel with sufficient backing |
| Line | Weight-forward floating line |
| Leader | 9-foot 3X or 4X leader |
| Tippet | 3X-4X fluorocarbon or nylon tippet |
| Flies | Variety of cicada patterns (sizes #6-#12) |
| Waders/Boots | Breathable waders and felt-soled boots (or rubber soles with studs) |
| Polarized Sunglasses | Essential for spotting fish and structure |
| Hat | For sun protection |
| Sunscreen | High SPF sunscreen |
A wading staff is also highly recommended, especially when fishing in faster currents. The Green River can be challenging to wade, and a staff will provide added stability. (Leave No Trace Center for Outdoor Ethics - always practice responsible angling)
Where to Fish on the Green River During the Hatch
The entire Green River is susceptible to the cicada hatch, but some sections are more productive than others. The section below Flaming Gorge Dam is particularly well-known for its hatches and large trout. The Grey Cliffs section and the Red Canyon section also offer excellent fishing opportunities. Access points are plentiful, but be sure to check current regulations and obtain any necessary permits. (USDA Forest Service - Bridger-Teton National Forest)
Consider a Guided Trip
If you’re unfamiliar with the Green River or want to maximize your chances of success, consider hiring a local guide. A good guide can provide valuable insights into the hatch, recommend the best flies, and help you navigate the river safely. They can also teach you advanced techniques and improve your overall fly fishing skills. I offer guided trips myself, and I’ve seen firsthand how much a guide can enhance the experience.
Respecting the Environment and Practicing Ethical Fly Fishing
The Green River is a precious resource, and it’s our responsibility to protect it. Always practice Leave No Trace principles: pack out everything you pack in, minimize your impact on the environment, and respect wildlife. Handle fish carefully, using wet hands and avoiding unnecessary stress. Consider using barbless hooks to minimize injury to the fish. And remember, a successful fishing trip isn’t just about the number of fish you catch; it’s about enjoying the beauty of nature and preserving it for future generations.
The Green River cicada hatch is a truly special event. With a little preparation and the right approach, you can experience some of the most exciting and rewarding fly fishing of your life.
